This photo and the following
description was published in the Eastern Daily Press newspaper:

"A recent addition to the collection
at the Strangers Hall museum in 1964 was this Norfolk hammer or hammered
dulcimer, seen in the foreground. The instrument is played either by
striking the string with a small hammer or plucking it with a hooked rod.

(The instrument in the background is
an accordzither a musical hybrid combining keys and strings made by the
Dresden firm of Muller.)"
